to use less space or to reduce transfer delays any more, but to or
ganize the valuable information differently. The multiresolution
structure on the new compression standards enables the fast an
efficient generation of low resolution products for a limited com
plexity. This new vision of compression advantages should lead
to an increase use of compression directly within image process
ing algorithms.

Binary stream
Figure 3: Example of bitstream organization for the LRCP order. To obtain the first quality layer, one just has to read the beginning of
the bitstream. However, to decode only one resolution level (Rq for example), or just a specific area of the image (Pi for example), the
decoder have to retrieve information in different part of the bitstream.

Figure 6: Impact of tile sizes on quality is neglectable (for realistic values). On the oposite, using tiles can greatly reduce the required
memory for processing.
